Creative Effects Challenge No. 239 - Gradient Map Random Noise

[tonyw]

This is a quick and easy challenge but with all sorts of possibilities to explore.  Basically it starts with any image or pattern and adds a Gradient Map adjustment layer with the Type of gradient set to Noise.  That creates colours which depend on the luminance of the underlying image.  So create an image layer - you could use an image , a pattern or use the brush to scribble (ideally use various shades of gray as that will give more colour variation).  Now add a Gradient Map adjustment layer and click on the Gradient to open the Gradient Editor.  In the box that says "Type" change it from Solid to Noise and you should see a variety of colours.  Click on "Randomize" and the colours will change.  Keep clicking and stop when you see one  you like!  You can also adjust the roughness setting which changes the colour transitions from very smooth to very sharp.   And, of course, changing the blend mode of the Gradient Map adjustment layer adds a whole different view of the image.  

Here's an example done in Elements 13 (It will work in any version of Elements, Photoshop as well as other Photo Editors) 

I started with a few scribbled lines on a white background using 3 different shades of gray:



I then used Liquify to push the pixels around to make more of a pattern.



I then added a Gradient Map adjustment layer, clicked on the gradient to open the Gradient Editor and changed the type from Solid to Noise so it looked similar to this:



Clicked on Randomize and got this:



Increased the Roughness to 70% and got this.



That's just one example - try it with any image, pattern or scribbling - doesn't have to be black and white as the gradient map doesn't recognize colour - only luminosity/brightness

Have fun playing around and looking forward to seeing your creations.
